About
Thread delegation and search is a capability of OpenAI's Codex coding agent. From within one Codex thread, the agent can search other threads, summarize their contents, link to them, and hand tasks off to them. It is intended for multi-thread, multi-project workflows where context and work are spread across separate conversations.
In a demo by YouTube creator Matthew Berman, a single thread located several existing "poem" threads and asked one of them to write a 50-word poem. The provided material does not include official documentation of the feature, so details such as availability by surface (app, CLI, IDE, cloud) and exact behavior are not confirmed here.
Codex is accessed through ChatGPT (Plus, Pro, Business, Edu, Enterprise plans), the desktop app, the IDE extension, the cloud agent, or the open-source Codex CLI, which is licensed Apache-2.0. It can also be used with an API key.
